Unicode character names primarily exist for identifying characters. That's why we have the stability for those names after all: unless it is very much misleading (like swapped Lao letters) we would like to stick to them as long as possible. For many scripts we can come up with some set of names that are suitable for identification. Han characters, among others, aren't. One can say that Han "characters" are identified by its shape, but a line between two differently perceived characters is extremely unclear. Some may recognize two characters as same, some not, some would even try to add a stroke or so to differentiate the character. Han characters are thus identified by providing multiple properties for them (the Unihan database), and the character names are just placeholders.
